Title: Information recording medium
Inventor: TSUNODA YOSHITO
IPC: G11B7/2433
Filed: 1984-04-20
Abstract: PURPOSE:To attain the real time record/reproduction with high S/N by laminating a reflection layer, a light transmitting material and a metallic thin film successively on a substrate. CONSTITUTION:A reflective thin film 14 containing at least one of metal such as Au, Al, Bi, In and semiconductor mainly is formed on a glass or plastics substrate 1. A single or composite film 15 containing a light transmitting material is formed on the film 14, and a recording material thin film 2 containing at least one of metals such as Au, Ta and a semiconductor is formed on the film 15. A laser light fulx 5 delivered from a laser light source 4 is converted into parallel light fluxes by a lens 6 and stopped down on the film 2 in the form of microspots by a semitransparent mirror 7 and a lens 8. Thus a hole 3 is formed and therefore the film 14 is exposed to the laser light flux which is made incident when the information is reproduced. The reflected light flux is detected by two photodetectors 16 and 17, and a differential output 19 is obtained by a differential amplifier 18. As a result, the noise components produced by the recessing/ projecting surface of the film 2 are offset.

Title: Control device for air-fuel ratio in internal-combustion engine
Inventor: KATSUNO TOSHIYASU
IPC: F02D41/00
Filed: 1985-04-15
Abstract: PURPOSE:To prevent air-fuel ratio from being excessively corrected, by detecting the element temperature of a sensor in the downstream side and stopping a control of the air-fuel ratio in accordance with an output of said sensor when the element temperature is less than a fixed value, in the case of an engine respectively providing air-fuel ratio sensors in the upstream and the downstream sides of a catalytic converter. CONSTITUTION:An internal-combustion engine, providing in its exhaust system a catalytic converter, provides in its upstream and downstream sides respectively the first and second air-fuel ratio sensors A, B, and in accordance with outputs of these sensors A, B an air-fuel ratio regulating means C controls air-fuel ratio in the engine. While here an element temperature discriminating means D, detecting an element temperature of the downstream side sensor B, discriminates whether or not this element temperature is in a fixed value or more. And when the element temperature is less than the fixed value, a stopping means E stops a control of the air-fuel ratio in accordance with the downstream side sensor B in the air-fuel ratio regulating means C. In this way, the engine, correctly discriminating the downstream side sensor B to be active or inactive, prevents an overrich and overlean state of the actual air-fuel ratio.

Title: High voltage generation set
Inventor: MIYAMOTO JUNICHI
IPC: G11C5/14
Filed: 1993-03-15
Abstract: PURPOSE:To grenerate stable high voltage by detecting the output voltage of a potential limiting means such as a limiter circuit and feeding back the information of the output voltage to a bypass means. CONSTITUTION:The gate of a MOSFET (Tr) 5 is connected between a limiter circuit 2 and a constant current source 4, and detects voltage 7 at one end of the constant current source 4. The set current value Ics of the constant current source 4 is set at that time. When the output currents Ipp of a high voltage generation circuit 1 is made smaller than the set current value Ics, the voltage 7 of the constant current source 4 is made lower than the threshold voltage of the Tr 5 of a current bypass circuit, thus preventing the on of the Tr 5. When the output currents Ipp are made larger than the set current value Ics, however, voltage 7 suddenly rises, and the Tr 5 is turned on. Consequently, a section larger than the set current value Ics in the output currents Ipp flows through ground potential threough Trs 5, 6. Accordingly, currents flowing through the Zener diode 2 are biassed to constant currents Ics, and the voltage is fixed.

Title: Potentiometer
Inventor: OTOBE TOSHIRO
IPC: H01C10/32
Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To lessen the influence on output characteristics by comprising a shaft, which engages with the bearing of a mounting base, and a rotor with an incline to abut on a cantilever, at its periphery. SOLUTION: When a rotor 23 is rotated, an incline 25 rotates. A cantilever 20 abutted against the incline 25 is displaced, according to the quantity of rotation of a shaft 24, and the resistance value of a distortion detecting element 21 provided at the cantilever 20 changes. A terminal 16 electrically connected to the circuit pattern 22 of a substrate 17 outputs this change of resistance value, with the inclination of the incline 25 of the rotor 23 being the quantity of rotation of the shaft 24 as an output signal. Then, the quantity of rotation of the shaft 24 is regulated by making the rotation regulation part 26 provided at the rotor 23 and the projection 15 provided at the mounting base 11 abut on each other. Hereby, even if it is used for a long time, the influence on output property is lessened without producing abrasion powder by rocking.

Title: Inverter high-voltage generator for x-ray
Inventor: HATAKEYAMA KEISHIN
IPC: H05G1/20
Filed: 1994-04-18
Abstract: PURPOSE:To lower the capacity of a power supply and remove troubles of higher harmonics of the power source by applying voltage of a filtering capacitor reaching a set value at the time of taking a picture to an inverter circuit and supplying electric power at the time of taking a picture only from the inverter. CONSTITUTION:The set value of voltage of a filtering capacitor 3, which is input voltage of an inverter circuit 4, set values VS1, IS1 of x-ray tube voltage and x-ray tube current, and picture taking time are set. When a preparation signal S11 for taking a picture is sent out from an operational unit 32, a current, voltage control circuit 17 brings the phases of the voltage and current to coincide with a single phase a.c. power source 30. Pulses are generated to drive switching elements 131-134 to make the voltage VS4 of the capacitor 3 a set voltage and a rectifying circuit 13 is controlled. When the voltage VS4 and the set value VS3 become the same, a signal 12 is sent out of the operational unit and the operation of the circuit 17 is stopped and at the same time the switching elements 131-134 are turned off. Consequently, though the output is high at the time of taking a picture, the x-ray exposure time is short, so that the a.c. power current can be set 0 by properly setting the electrostatic capacitance of the capacitor 3.

Title: Level shifter
Inventor: MAKINO HIROYUKI
IPC: H03K19/0952
Filed: 1984-04-17
Abstract: PURPOSE:To obtain a level shifter which shifts an input potential level with one normally turn-off MESFET, two normally turn-on MESFETs, and one voltage drop element. CONSTITUTION:When a signal input is in the low level of an earth potential, the potential in a node 26 is -phiB because the input signal has the voltage dropped by a Schottky barrier phiB by a Schottky diode 21. At this time, a normally turn- off MESFET23 is made conductive, and the potential of an output node 28 is lowered to the negative level -phiB. When a high-level signal having a potential VH is inputted, the potential in the node 26 becomes VH-phiB because of similar voltage drop of phiB. At this time, the FET23 is made nonconductive, and the potential of the output node 28 goes to the high level. Thus, the level shifter which shifts the input potential level is obtained.

Title: Optical information detector
Inventor: KURATA YUKIO
IPC: G11B7/1392
Filed: 1987-03-31
Abstract: PURPOSE:To prevent the deterioration in quality of a focusing error caused by the aberration of an optical system by interposing a turnable parallel plate tilted from an optical axis to a divergent or converging part of light in an optical path. CONSTITUTION:The astigmatism in a direction in parallel or not orthogonal to an information track remaining in the optical system is removed. That is, the direction of the astigmatism is controlled by turning a parallel plate 12 around the optical axis 13 and the quantity of astigmatism is controlled by varying a tilt angle theta of the parallel plate or using the parallel plate different in plate thickness (t) and refractive index (n). Thus, it is prevented that the aberration of the optical system influences the diffraction pattern by a guide track projected onto a photodetector, resulting in deteriorating the quality of a focusing error signal.

The thin piece is moved to an open position, the fixation of the horizontal bar 410 is released to move it to the right position, the member 410 is clamped in this position, and the thin piece is moved toward the member 410 until it contacts and stops.  This contact position is taken as the standard position to measure the position of the thin piece.
